I know someone can help me on this one.

A while back I ran across some interesting 3 terminal temperature
sensors, and now that I'm about to design one in, I can't find the WWW
link to them for design info.

These devices are unique in that the temperature is transmitted via
the on/off ratio of the pulse train from the 3rd terminal of the
device.  They are factory calibrated, and I think they come in TO3
cases.

Anybody recognize these?

TIA - Martin.
